Formulas are used to define the relational values between objects and to create predictive behavioral patterns when associated constraints are modified.

Simple formulas are used to fix an object’s position in relation to other objects and are commonly referred to as a Design Rule. In the example below, the variable for D4 will be fixed to always be half of the value of D3, thus when D3 (150) is updated, the associated value of D4 will be correspondingly updated.

The condition of the constraint markers can be changed using the Preferences options. Below are the default color settings for the constraint markers. This is a system setting, invoking all new changes on new sketches until changed by the user.
